W. F. PERSONS. AUIOIVIOBILE LAMP. APPLICATlON FILED OCT. nu ma PatentedApr. 3,1917.

mm mo a citizr r'can be ma 3 is a detail sectional view F; PnnsoNs', ofthe United States, residing at Lakewood, in the county of Cuyahoga andState of Ohio, have invented. a certain new and useful Improvement inAutomobile amps, of which the following is a full clear, and one ctdescription, reference being had to the accompanying drawings.

This invention relates generally to lamps and more particularly to anautomobile headlight lamp.

' The object of the invention is to improve c it known that I, l/VILLIAMtheconstruction of automobile headlights particularly withu'efcrence tothe manner of securing the glass and reflector to the body of the lamp.

ll ith this object in view the invention consists essentially inconstructing the body of the l holding ring curved along its inner edgeto engage the glass and flanged along its outer edge toembrace the bodyportion of the lamp, the glass holding ring being secured by means of adivided clamping ring adapted to embrace the glass holding ring and theouter portion of the lamp body.

The invention consists tails of construction all of which will be:t'ully described hereinafter and pointed out in the appended claims.

In the drawings forming a part of this specification l have illustratedone embodiment of my invention, but it will be under stood that certainchangesor modifications de within the scope 7 111 these drawings Figurel is a face view of an automobile lamp embodying my invention, partsbeing broken away to illustrat-c certain details of construction; F ig.is a vertical longitudinal section of the lo. 13' Fig. is a detailperspective view of the clamping ring; Fig. at is a sectional persp:tive of the glass holding ring; Fig. 5 illustrating the means forfastening the ends of the clampmg ring; and Fig. 6 is an enlarged detailsectional View illustrating the relative positions of the various partswhen properly assembled.

upon thls also in certain dc-- of the claims.

28 carried in the end rammed Apr. 3, 191 7. Serial No. 126,264.

In carrying out my invention I employ an outer shell or body 10 whichmay be of any shape desired, the forward outer edge thereof being rolleddownwardly at 11 and inwardly at 12, the portion 12 being flat and atright angles to the portion 11 as most clearly shown in Fig. 6. A slightshoulder the lam body, and this flange of the reflector is pre erablyformed with an annular groove or recess 16 in which seats the packingring 17, of any suitable material; and resting packing ring is thecircular glass plate or glazing l8.

In practice, prefer to soposition the anthe reflector with its packingring, I, employ a continuous glass holding ring 19,

the inner portion thereof being curved as shown at 20 so as to contactwith the glass adjacent its outer edge, and the outer portion of thisring is flanged as shown at 21 in order to embrace the outer edge of thelamp body, and between the flanged portion 21 and/the curved portion 20there is formed an inwardly extending shoulder 22 which is adapted tocontact with the inturned edge 12 and properly position the glassholding ring.

glass holding ring against displacement I provide a clamping ring 23lhvided at 24 and having upset-ends 25 and 26, the end 26 being shapedto receivev the end 25 therein and provide a perfectly smooth joint. Forthe purpose of drawing the ends of the clamping ring together andbinding the entirh ring as a whole tightly about the lamp body and glassholding ring, I employ a screw 27 working in the threaded member 25, andif desired' a similar shaped member 29 may be inserted in the offset end26 for the purpose of strengthening the same and through which the screwworks as mostolearly shown in Fig. 5.

The clamping rin is curved or of such cross sectional shape as toembrace the shouldered portion of the glass holding ring and also theshoulder 13 upon thelamp body, and it is obvious that when the ends of:the ring are drawn together and the ring as a whole contracted it willbe firmly bound upon the lamp body and all of the parts will be securelyfastened in their proper positions.

A. lamp constructed as herein shown and described is easy to.nianufactru'e, and the parts can be quickly and easily assembled andfastened or untastened and separated, and all of the parts so coact andcooperate one with the other, as to insure accuracy of adjustment in thefinal manipulation.

Having thus described my invention, what I claim is:

1. In a'lamp, the combination with a body portion, of a reflectorarranged therein, a glass in advance of said reflector, a glass holdingring contacting with said glass, and an exterior clamping ring engagingand embracing an edge of the glass holding ring and body ofthe lamp.

2. 'In a lamp, the combination with a body portion, of a reflectorpositioned therein, a glass in-advance of said reflector, a sheet metalglass holding ring contacting with said glass adjacent the outer edgesthereof, and a divided exterior clamping ring adapted to engage theglass holding ring and lamp body.

In a lamp, the combination with a body portion, of a reflectorpositioned therein, a glass contactingwith said reflector, a continuousflanged glass holding ring contacting with said glass, a dividedexterior clamping ring adapted to engage said glass hold ing ring andthe body of the lamp, and means for contracting said clamping ring uponsaid glass holdlng ring.

In a. lamp, the combination with a body portion, of a reflectorpositioned therein, a, glass in advance of said reflector, a flangedsheet metal glass holding ring contact-111g with said glass adjacent itsouter edges, a divided exterior clamping ring adapted to engage theglass holding ring and lamp body, the ends of said divided ring beingupset, and a screw working in said upset ends for drawing the sametogether.

In a lamp, the combination with a body portion, of a reflector and glasspositioned therein, a continuous glass holding ring adapted to embrace.the outer edges of the lamp body and contact with the glass, and anexterior clamping ring adapted to engage the glass holding ring andlamp-body.

(3. In av lamp, the combination with a. lamp body having a reflector andglass positioned therein, of a continuous flanged glass holding ringadapted to contact with the glass" and embrace the outer edges of thelamp body, and an exterior clamping ring adapted to engage the glassholding ring and the lamp body.

7. In a lamp, the combination of a body portion, of a flanged reflectorpositioned therein, a glass positioned upon said reflector, acontinuous, flanged, glass holding ring contacting with said glass andembracing the outer edges 01'' the lamp body, a divided exteriorclamping ring adapted to engage the glass holding ring and lamp body,and

7 means for drawing the ends of said divided ring together.

8. In a lamp, the combination with av body portion having an inwardlyrolled front edge, of a flanged reflector, a glass, and a glass holdingring, said ring being flanged, shouldered and curved, a divided clampingring curved in cross section, and means for contracting said clampingring.

In testimony whereof, I hereunto ailix my signature.
